University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    BIOCHEMICAL STUDIES ON THE DEVELOPMENT OF CORKY TISSUE IN SAPOTA (Manilkara achras (Mill.) Fosberg)
    (University of Agricultural Sciences, Bangalore, 2009-07-15) JAYA, JOSHI; Shivashankar, S.
    Corky tissue (CT) of sapota is a physiological disorder characterized by hard lump in the pulp, slightly desiccated in nature and acidic to taste. This disorder shows no distinct external symptoms and becomes visible only w hen fruit is cut open. Under extremely severe conditions, corkyskin eruptions are seen. Corky tissue incidence is estimated to vary from 2 0 to 5 0 percent in Cricket Ball, while in other varieties like Kalipati it is up to 5 percent. Biochemical analysis reveals that total and reducing sugars, soluble protein and activities of amylase and lipase were higher in the me socarp of healthy fruits compared to CT affected fruits, while content of starch and free am in of acids were lower. These indicated that degradation of starch into sugars wash ampered in CT affected fruits. Starch content, soluble protein and free amino acid were higher in health y seed s than seeds from CT affected fruits, while total and reducing sugars and amylase activity were lower. Under field conditions, regulation of sink strength by exogenous application of GA3 and PBZ showed that, CT occurred in the weaker sink thus confirming the role of inter fruit competition in CT development. Seed viability seems to play an important role in CT development. Sink strength of fruit depends upon number of viable seeds it has. Moisture content in seed and mesocarp of healthy fruits washigher in comparison with that of CT affected fruits, showing there by that seed from CT affected fruits had lost moisture leading to reduction in seed viability. Reduction in seed viability in corky tissue affected fruit was confirmed by data on germination, dehydrogenase activity, DNA content and analysis of endogenous levels of GA3 , ABA and JA using HPLC . Conditions of increased temperature, evaporative dem and and decreased relative humidity showed marked in crease in cork y tissue incidence.

    Biochemical and histochemical analysis of black pepper (Piper nigrum L.) inoculated with mycorrhiza from different crop management systems
    (University of Agricultural Sciences GKVK, Bangalore, 2008-08-08) RAJESH, K. V.; SURESH, C. K.
    The investigation was carried out to study the biochemical, histochemical analysis of Piper nigrum L. and Sorghum bicolor (L.) Moench inoculated with mycorrhiza from different crop management systems. Black pepper and sorghum were inoculated with mycorrhiza from the organic soil, inorganic soil, natural soil, control and Glomus fasciculatum. There were three experiments in which the first experiment was on growth response of black pepper to the inoculation of mycorrhiza from different crop management systems. In second experiment black pepper and sorghum were inoculated with mycorrhiza from different crop management systems and in third experiment sorghum was inoculated with mycorrhiza from different crop management systems. Histochemical analysis of these crop plants were carried out to study the difference in the accumulation of the polysaccharides, proteins and nucleic acids in leaf tissues of control and mycorrhiza inoculated plants. Plants inoculated with Glomus fasciculatum showed highest rooting percentage, percent root colonization, phosphorus, potassium and nitrogen content. Plants inoculated with Glomus fasciculatum recorded increased biomass than control. A significant difference in the accumulation of polysaccharides, proteins and nucleic acid content was observed in leaf sample of the plant inoculated with Glomus fasciculatum.

    Effect of exogenous Lipopolysaccharides (LPS) of different strains of Rhizobium on nodulation in chickpea (Cicer arietinum L.)
    (University of Agricultural Sciences GKVK, Bangalore, 2009-09-17) SHANMUKHAPPA, H. AMASI.; Uma, S. Podder.
    The present investigation was carried out to study the effect of exogenous Lipopolysaccharides (LPS) of different strains of Rhizobium on nodulation in chickpea (Cicer arietinum L.). The lectin was isolated from chickpea seed and root to see the effect on Lipopolysaccharides (LPS) which were isolated from four chickpea specific Rhizobium strains namely IC-59, IC-1148, IC-2091 and IC-149 and one non specific Rhizobium strain P-132. The strain specific lipopolysaccharides of specific strains of Rhizobium inhibited lectin induced agglutination of Rhizobium specific to chickpea. And agglutination was observed higher in case of seed lectin than that of root lectin, as there was no agglutination with non specific strain so no inhibition of lectin was observed. This was also supported by the binding study data that chickpea root lectin binds more strongly to homologous Rhizobium than seed lectin. So that higher concentration is needed for replacement of lectin from Rhizobium. Number of lectin binding sites per Rhizobium is three to four times more with respect to chickpea specific strains as compared to non specific strain. Nodulation experiment showed all the chickpea specific Rhizobium strains formed nodules in in vitro experiment whereas non specific strain does not form any nodules. This follows the dictum all or none phenomenon. In other words, nonspecific Rhizobium does not inhibit agglutination and nodulation upon addition of exogenous LPS

    STUDIES ON BIOCHEMICAL CHANGES AND SEED QUALITY AS INFLUENCED BY OSMOCONDITIONING IN ONION (Allium cepa L.)
    (University of Agricultural Sciences GKVK, Bangalore, 2007-08-21) VEENA, M. K.; THIMMAIAH, S. K.
    The seeds of two cultivars of onion, viz., Arka Kalyan and Rampur Rose were subjected to acceralated ageing at 40°C and 100 per cent RH under laboratory conditions for 0 & 8 days to create two vigour levels viz., high (non-aged) and low vigour seeds. Then they were osmoprimed with PEG-6000 at -1.5 MPa & -1.0 MPa for 5 days and 7 days at 10°C in order to assess the ability of priming treatments in repair of deterioration sustained during ageing. In the present investigation, it was observed that the PEG priming had increased the seed quality parameters such as germination percentage, mean seedling dry weight, SVI and the biochemical parameters, viz., total soluble sugar, protein and lipid content; total dehydrogenase and β-amylase activities in the seeds; but decreased the EC, total soluble sugar and protein content in the seed leachate; MDA content in the onion seeds of both the cultivars namely, Rampur Rose and Arka Kalyan studied. Further, the SDS-PAGE banding pattern of soluble seed protein profiles showed more variation with respect to band number and intensity in Rampur Rose as compared to that of Arka Kalyan upon PEG priming. In overall, it can be concluded that the high vigour seeds of Rampur Rose showed better improvement with regard to seed and seedling vigour upon PEG treatment at -1.0 MPa for 7 days as compared to other treatments.
